Redirect from HTTP to HTTPS NGINX?

Question

Nginx

There is a site to which I connected an ssl certificate, if I register site.io in the browser, it does not automatically transfer me to https://site.io , but gives an error.

Answer 1

server {
        listen site.io:80;
        server_name site.io;
        return 301 https://$server_name$request_uri;
}
